FDCAN TT operation control register
| SGT | Set global time.  |  
| ECS | External clock synchronization.  |  
| SWP | Stop watch polarity. 0 (B_0x0): Rising edge trigger 1 (B_0x1): Falling edge trigger  |  
| SWS | Stop watch source. 0 (B_0x0): Stop watch disabled 1 (B_0x1): Actual value of cycle time is copied to FDCAN_TTCPT.SWV 2 (B_0x2): Actual value of local time is copied to FDCAN_TTCPT.SWV 3 (B_0x3): Actual value of global time is copied to FDCAN_TTCPT.SWV  |  
| RTIE | Register time mark interrupt pulse enable. 0 (B_0x0): Register time mark interrupt output disabled 1 (B_0x1): Register time mark interrupt output enabled  |  
| TMC | Register time mark compare. 0 (B_0x0): No Register time mark interrupt generated 1 (B_0x1): Register time mark interrupt if time mark = cycle time 2 (B_0x2): Register time mark interrupt if time mark = local time 3 (B_0x3): Register time mark interrupt if time mark = global time  |  
| TTIE | Trigger time mark interrupt pulse enable 0 (B_0x0): Trigger time mark interrupt output fdcan1_tmp for more than one instance and fdcan_tmp if only one instance disabled 1 (B_0x1): Trigger time mark interrupt output fdcan1_tmp for more than one instance and fdcan_tmp if only one instance enabled  |  
| GCS | Gap control select 0 (B_0x0): Gap control independent from event trigger 1 (B_0x1): Gap control by input event trigger pin  |  
| FGP | Finish gap. 0 (B_0x0): No reference message requested 1 (B_0x1): Application requested start of reference message  |  
| TMG | Time mark gap. 0 (B_0x0): Reset by each reference message 1 (B_0x1): Next reference message started when register time mark interrupt FDCAN_TTIR.RTMI is activated  |  
| NIG | Next is gap. 0 (B_0x0): No action, reset by reception of any reference message 1 (B_0x1): Transmit next reference message with Next_is_Gap = 1  |  
| ESCN | External synchronization control 0 (B_0x0): External synchronization disabled 1 (B_0x1): External synchronization enabled  |  
| LCKC | TT operation control register locked. 0 (B_0x0): Write access to FDCAN_TTOCN enabled 1 (B_0x1): Write access to FDCAN_TTOCN locked  |
